Ivo Shandor:If you get rid of the otters, the local sea urchin population will expand. Sea urchins will eat the roots of kelp, causing the rest of the plant to float away. Fish that formerly lived in the kelp forest will also leave. Hope you like eating sea stars.

And the Otter population will expand as well.

Why is it, that the most vehemently anti-naturalistic, anti-environmental capitalists see dollar signs every time they look at an undisturbed area, then complain and blame what already existed before they came to the area when their efforts to strip the area of it's value are successful?
